  • 1.  Messaging Gateway: unable to backup via FTP

    Posted Jan 12, 2012 10:33 AM

    When I tried doing a Backup To a remote location using FTP, I am consistently getting the following error message regardless what I put in:

    Cannot backup the database on the remote host.
    FTP:Can't transmit the file: Access is denied. ERROR: Unable to send to the specified URL.

    What I don't understand is why I can still upload to the same ftp credentials using an FTP application such as Filezilla, but still can't with the Messaging Gateway backup feature.  Please help, thanks.

    Here's an example of how it appears:

    Backup Data -> Full Backup

    Backup To -> Store backup on a remote location using FTP

    Host/IP address:  192.168.10.34

    Port: 21

    Path: / (I tried "\" also)

    Requires authentication (correct username & password entered)

    This would typically need a packet capture to understand what exactly is failing.

    Keep in mind that the Messaging Gateway will use PASV FTP. This can sometimes cause issues with firewalls becuase the firewall will only have port 21 open and won't allow access to the random high port number that we will try to transmit on. I have seen this cause the error you are reporting.

    Thanks for quick reply.  I'm not sure what are the correct steps to perform a packet capture since I'm only familiar with the GUI interface so far.

    You would need a program such as Wireshark installed on the FTP server capturing the traffic. Once you have the capture running, perform the backup. Once the error shows up, stop the capture. You can then view the FTP conversation and right-click one of the packets and choose 'Follow TCP Stream.' You will then be able to view the conversation in plain text and see any errors.

    If what you see does not make any sense, you can post the .cap file here and one of us can look at it. You may need to end up calling in and opening a ticket so we can give this more attention and a more immediate analysis.

    In attached file (rename backuptest.txt to backuptest.pcap) I can at least see in line 71 the 550 access is denied message at least.  Otherwise the rest I could only seem to make heads or tails.  Thanks in advance.

    Here's the follow TCP stream as it would still appear similar to how I'd normally FTP through filezilla :/

    220 Microsoft FTP Service
    user acibackup
    331 Password required for acibackup.
    PASS acibackup
    230 User logged in.
    TYPE I
    200 Type set to I.
    PASV
    227 Entering Passive Mode (192,168,10,34,253,175).
    STOR /test.full.manual.tar.bz2
    550 Access is denied.

    I may need to call in to open a ticket as this is getting desperate.

    As an update, it turned out I needed to use the administrator credentials, and then it worked as desired.  Thanks for the assistance.

    This looks like some sort of permissions issue with using the STOR command. Glad you were able to resolve it by using an administrator account.
